Not getting any results back from a raw query in Laravel - php

Question

I have a raw query and when I run this query in phpMyAdmin it returns 3 results but when I try to use Laravel Query Builder I get an empty array.
My query
SELECT id, reply_text, sending_time
FROM sms_sender_inbox_replies
WHERE phone_number
IN ('[phone]', '[phone]', '[phone]')
AND id IN (
SELECT MAX( id )
FROM sms_sender_inbox_replies
GROUP BY phone_number
)
Result:
+----+-----------------+---------------------+
| id | reply_text | sending_time |
+----+-----------------+---------------------+
| 87 | This is a test | 2019-07-30 08:25:26 |
| 54 | And another one | 2019-07-29 06:35:11 |
| 12 | Last test | 2019-06-16 09:44:26 |
+----+-----------------+---------------------+
But when I try to do this query with Laravel I get back an empty array []
dump($phone_numbers);
// 0 => "[phone]"
// 1 => "[phone]"
// 2 => "[phone]"
$phone_numbers = implode("','", $phone_numbers);
dump($phone_numbers);
// [phone]','[phone]','[phone]
dump("SELECT id, reply_text, sending_time
FROM sms_sender_inbox_replies
WHERE phone_number IN ('$phone_numbers')
AND id IN (
SELECT MAX(id)
FROM sms_sender_inbox_replies
GROUP BY phone_number
)");
// SELECT id, reply_text, sending_time
// FROM sms_sender_inbox_replies
// WHERE phone_number
// IN ('[phone]', '[phone]', '[phone]')
// AND id IN (
// SELECT MAX( id )
// FROM sms_sender_inbox_replies
// GROUP BY phone_number
// )
$replies = DB::connection('second_connection')
->select("
SELECT id, reply_text, sending_time
FROM sms_sender_inbox_replies
WHERE phone_number IN (':phone_numbers')
AND id IN (
SELECT MAX(id)
FROM sms_sender_inbox_replies
GROUP BY phone_number
)
", ['phone_numbers' => $phone_numbers]);
dump($replies);
// []
P.S. Here is the output of the Query Log
I can't understand why it is returning an empty array. But when I run the raw query in phpMyAdmin it returns results so I know that the query is correct.
Array
(
[0] => Array
(
[query] =>
SELECT id, reply_text, sending_time
FROM sms_sender_inbox_replies
WHERE phone_number IN (':phone_numbers')
AND id IN (
SELECT MAX(id)
FROM sms_sender_inbox_replies
GROUP BY phone_number
)
[bindings] => Array
(
[phone_numbers] => [phone]','[phone]','[phone]
)
[time] => 0.7
)
)

When you bind it like that, you try to find the phone_number IN as a single value (not as 3 values). A placeholder can only be to a single value, not to an array - but you can work around this using the QueryBuilder methods, which simplifies bindings.
$phone_numbers = ["[phone]", "[phone]", "[phone]"];
$result = DB::connection('second_connection')
->table('sms_sender_inbox_replies')
->select('id', 'reply_text', 'sending_time')
->whereIn('phone_number', $phone_numbers)
->whereIn('id', DB::table('sms_sender_inbox_replies')
->selectRaw('MAX(id)')
->groupBy('phone_number')
->get())
->get();
